5. What good are antiviral drugs?
Antiviral drugs taken within 48 hours of the first symptoms -- such as a
sudden fever -- make the illness less severe. The sooner after infection these
drugs are taken, the better.
The H5N1 bird flu is resistant to an older and less potent class of flu
drugs, which includes Symmetrel and Flumadine. These drugs won't work and would
not be used in bird flu pandemic.
Newer and more effective flu drugs, Tamiflu and Relenza, can still work
against H5N1 viruses. However, several bird flu viruses isolated from infected
humans have already become resistant to Tamiflu.
Relenza is sprayed in the nose. It is extremely effective at neutralizing
flu viruses. But people who get bird flu from poultry tend to get infections
deep in their respiratory tracts. It's not at all clear that Relenza could
reach such deep-seated infections.
